[Mailman-Users] Mailman installation problem : "User unknown in relay recipient table"

Together with the proper A and MX records for "mydomain.com", I have a fresh Ubuntu 12.04LTS server. I have followed the "http://library.linode.com/email/mailman/ubuntu-12.04-precise-pangolin" and installed Mailman. I have created a few lists through the web interface.

One important problem I came accross is not being able to send message to any of the lists. The members do receive the "Welcome to the list" message from the server, but Whenever any member of any list sends a message to the list, s/he immidiately receives a message saying

<test at lists.domain.com>: host lists.domain.com[] said: 550 5.1.1 <test at lists.domain.com>: Recipient address rejected: User unknown in relay
recipient table (in reply to RCPT TO command)

I have tried Ubuntu Forums, and was advised to check the thread "http://mail.python.org/pipermail/mailman-users/2011-January/070896.html". I have followed this thread and added


into mm_cfg.py, and also added "hash:/var/lib/mailman/data/aliases" at the end of the line starting with "alias_database" and "alias_maps" in the file main.cf of postfix. But unfortunately I ended up with a setup responding "mail for lists.domain.com loops back to myself" for every message sent to the list. At the end of the thread, the gentelmen who seems to found a solution, points to a howto page, which does no longer exists.

So I reverted my setup back to the "User unknown in relay recipient table" situation.

Any help appriciated.
